If I have a parent Node2D with transform's translation at (50, 0) and a child Node2D with transform's translation at (100, 0).
When I type parent.position, I get (50,0).
When I type child.position, I get (100,0).
These are their respective node's relative position, but not the absolute position in the world. The child's absolute position is its relative position added to the parent's relative position: (50,0) + (100,0) = (150, 0)
How do I get the absolute position of a node?
